Yüksek yapılar ortaya çıktığı ilk dönemden bu yana her zaman değişim ve gelişim içerisindedir. Çok katlı yapıların gelişimi incelendiğinde fonksiyon bakımından daha çok ofis işleviyle kullanılmaktadır. Fakat çağımız kent yaşamının değişen ekonomik, sosyal ve kültürel gereksinimlerine göre bu oran giderek azalmakta ve çok katlı yüksek yapılarda ofis kullanımının yerini konut kullanımına bıraktığı görülmektedir. Dünya genelinde yüksek yapıların %45'inin ofis yapısı olarak kullanıldığı görülürken Türkiye'de ise bu yapılar %50'den fazla oranda konut işlevindedir. İnsanlar zamanlarının büyük bir kısmını konutlarda geçirmekte olup, yüksek yapıların da kullanıcılarına standart bir konut konforunu sunması gerekmektedir. Bu çalışmada, giderek yaygınlaşma eğilimi gösteren yüksek konut yapılarındaki fiziksel iç çevre koşullarını oluşturan parametrelerin iç ortam konforu üzerindeki etkisi incelenmiştir. Seçilen ulusal ve uluslararası yüksek konut örnekleri, iç ortam kalitesini belirleyen parametrelere göre karşılaştırılmıştır. Yeni yüksek konut yapı üretiminde; tasarım, planlama, teknoloji, malzeme ve uygulama alanlarında; fiziksel çevre koşullarının, kullanıcı sağlığını olumsuz yönde etkilemeyen ve onların performansını/verimliliğini artırırken enerji verimliliği de sağlayan yöntemler belirlenmeye çalışılmıştır. Yüksek yapılar çevreye saygılı, enerji verimli ve sürdürülebilir olarak tasarlanabilmektedir. Ancak yüksekliğin arttığı her metrede bu niteliklerin etkin olarak yapıda uygulanabilirliği de azalmaktadır. Çalışmanın sonucunda, yüksek bir konut yapısında ideal iç ortam kalitesini sağlamakta en etkili öğenin yapı kabuğu olduğu görülmüştür. Yapı kabuğunun tek cidarlı olarak tasarlanması, iç ortam kalitesinin kullanıcı güvenliğiyle birlikte sürdürülebilirliğini kısıtlayabilmektedir. Fakat çift cidarlı olarak tasarlanan yapı kabuğunun katmanlı yapısıyla ısıl konforun, doğal havalandırma olanağıyla temiz iç hava kalitesinin, ses yalıtımı özelliğiyle akustik konforun ve güneş kontrol elemanlarıyla aydınlatma konforunun iç ortam kalitesini ve kullanıcı güven-liğini daha kolay ve sürdürülebilir şekilde sağlayabileceği belirlenmiştir. High-rise buildings are constantly changing and developing since they first began to be constructed. When the development of high-rise buildings is examined, most are found being used as offices. However, according to the changing economic, social and cultural requirements of contemporary urban life, this function has been declining, and high-rise office buildings have been replaced with residential apartments. Although high-rise buildings are still primarily used as offices around the world (45%), more than 50% are used as residential buildings in Turkey. As people spend a considerable amount of time in residential spaces, high-rise buildings must also offer standard residence comforts to their users when functioning residentially. In this study, the influence of physical indoor environment parameters in high-rise residential buildings on their indoor environmental quality (IEQ) is examined. Se...
The building envelope, the most important element in the energy consumption of a building, gains more importance due to the large amount of the surface area of building’s façade in high-rise buildings. The energy consumption of these buildings is increasing depending on their high transparency ratio as a result of decrease in the thermal resistance of the façade. The aim of this study is to show the importance of building envelope design in energy efficiency of high-rise residential buildings and to analyze the effect of the building envelope design on energy consumption. Turkey’s highest residential building from 2010 to 2017 was selected for the case building. DesignBuilder program with the EnergyPlus simulation engine was used for energy analysis of the building. The energy consumption results were compared with the other study data in the literature. As a consequence of the simulation conducted according to the existing façade of the building, 25% of the energy is used for heating and 14% for cooling in total energy consumption. It has been found that the building envelope designed with double-layered air corridor can offer the maximum level of residential comfort to the occupants. This study shows that the building façade with air corridor also reduces energy consumption by 30% compared to the same sized buildings.
In today's living conditions, the quality of life depends on wellmanaged energy. Therefore, countries produce different energy policies to manage their energy resources. Determining appropriate, feasible, and controllable energy policies becomes important especially for buildings, as being one of the most significant energy consumers. Green building certification systems (GBCSs) are one of the most common applications for energy efficiency in the building sector. Purpose This paper is a comparative analysis of GBCSs in developed and developing countries, in an effort to establish the similarities and differences between Turkey's first national GBCS-B.E.S.T and other GBCSs, and to determine how the energy criteria in GBCSs contribute to each dimension of sustainability (i.e., environmental, economic, social). Design/Methodology/Approach The research methodology depends on the literature review and documentary review on energy-related regulations, legislation, and laws. A comparative analysis of GBCSs was conducted in the study. Not only the sub-criteria directly exist under the energy criterion, but also
PurposeThis study aims to evaluate the use of open and green spaces (OGS) of a historical building after the adaptive reuse of the building. The relationship between the use of OGSs and the perceived environments of the users is examined.Design/methodology/approachTo determine the OGS use preferences of the users and to obtain quantitative data, a survey was conducted. The data were evaluated using descriptive statistics in SPSS. Also, observation method was used to determine the frequency measurements of OGS. Thus, the relationships between the results were identified statistically.FindingsIt has been determined that the outdoor space features of a historical building should be arranged following its new function. The use of OGSs was affected by the physical properties of the spaces, accessibility and time spent in the settlement.Originality/valueThe historical building itself and its interior spaces, as well as the open, semi-open and green spaces of the building, are affected by the adaptive reuse process. However, the fact that only a few studies in the literature focus on the outdoor environment of the re-functionalized historical buildings makes this study original and unique.
Healthcare facilities have an important place in Ottoman Architecture. Started to be built during the Anatolian Seljuk period and continued into the Ottoman in many cities, they manage to survive. However, it is not possible to use them with their original functions today. Most of them are used by serving as exhibition and museum buildings like Edirne Sultan 2nd Beyazid Health Complex. In the use of such historical buildings, the examination of their response to changing living conditions and needs is important. This study investigates how the physical environment affected the design of the complex, and the impacts of its planning and building envelope on today’s IEQ. The physical environmental data were discussed about thermal, daylight, ventilation, and acoustics performances by calculating and evaluating the existing energy consumption of the building. Methods like literature review, direct observation, on-site examination, simulation, and documenting with photographs were used. It was determined that five hundred years ago, the building was compatible with its physical environmental data in terms of its function, planning, and building envelope, and, as being a museum today, it provides all the necessary comfort conditions for its users, and that the energy consumption is at an acceptable level.
